Bought this nearly immaculate Sony EX-618 for a very reasonable £28 off eBay. Needed a new belt and a good clean up of the battery door contact...
The fact the mechanism is tensioning the tape when a battery is inserted is a good sign. I still think there could be a bad connection between the...
I don't think connecting power with the caps removed would cause damage to the IC's. I would do a continuity test on the power and ground...
There is an electrolytic capacitor across the motor supply, I think it's C314 330uF in the bottom right hand corner of the schematic close to the...
Did you fully reassemble the Walkman before checking the audio? Sometimes the case screws or metal contacts are used as part of the grounding...
Most personal stereo amps range from 5mW to 30mW RMS per channel into 32 Ohms. 0.5W will be at the maximum rail voltage and the lowest load...
Did you have headphones plugged in? There is a switch in the headphone socket so that power is only supplied when they are plugged in. Check if...
I thought I'd better update this post as stuck-in-time very kindly shared his pdf design for all variants of the WM-30 / WM10ii window, you can...
I had one of these when I was a kid but it was stolen from my school bag. Bought another on eBay last year for about £20, still fun to play now...
I agree with Silver965, if you have multiple WM-F63 with the same issue it does point towards failing electrolytic capacitors. Rather than...
Yes they are interchangeable. No, they won't make much difference to the sound quality. Some audiophiles might disagree but I doubt you'll notice...
I would replace with surface mounted tantalum capacitors if you can't find any electrolytics.
Do you have a digital multimeter that can read voltage, continuity and resistance? If yes then you can start by measuring the voltage at the...
The service manual and schematics are available from Elektrotanya so you could measure the voltages at pre amp IC301 and Dolby chip IC302. From...
Possibly a disconnected ground wire between the head and the circuit board.
Stuck-in-time, you are a star, they look amazing! So much better than anything I could have done! Thank you so much for sharing. You even did all...
Thanks, that would be great. My attempts to draw the graphics have been unsuccessful.
I'm still looking for vectors or artwork for my WM-30 window, if anyone has them?
It might not be so bad after a good clean up. I've owned one of these since new and the paint is a bit worn through in places but it looks period...
I won't be starting for a few months when I have access to a laser printer.
